ELIZABETH J. ROBINSON, OF ARLETA, OREGON.

DISH-WASHI G MACHINE.

To all whom it may concern: 1

Be it known that I, ELIZABETH J. ROBINsON, a citizen of the United States, residing at Arleta, in the county of Multnomah and State of Oregon, have in-' 5 vented new and useful Improvements in Dish-Washing Machines, of which the. following is a specification.

The invention relates to a dish washing machine.

One ofthe primary objects of the invention is the provision of means for supporting articles to be washed in various localities in the machine.

Another object of the invention is the provision of means for supplying water throughout the interior of the area of the machine so that the articles will come in contact with the water and be thoroughly cleansed without being handled by the operator I A further object of the invention is the provision of means for shifting the supporting means, such as shelf sections for receiving articles to be cleaned in alposition so as to occupy the least possible space within the machine, and to allowaccess to the bottom of the latter. 1 I Astill further object of the invention is the provision of article supporting means such as shelf sections, one adapted to be shifted on to the other, and at least one of the sections of each supporting means being hingedly connected at the interior of the machine.

Other objects of the invention are the simplicity of construction, efficiency of operation, durability and inexpensiveness of the manufacture;

With these and otherobjects in view the invention, for example, consists in the construction, combination and arrangement of parts hereinafter described and the preferred form of construction as embodied in the accompanying drawings, and it is to be understood that I may make such changes, variations and modifications as comeproperly within the scope of the claims hereunto appended without departing from the spirit of the invention. In the drawings:-Figure l is a perspective view of the machine; Fig. 2 is a vertical longitudinal section;

' 40 Fig. 3 is a section taken longitudinally of the shafts carrying the blades; Fig. 4 is a detail perspective view of the skeleton shaft and blades carried thereby; Fig. 5 is a top'plan view of one of the removable trays Fig. 6 is a longitudinal section of the shiftable supporting shelf sections and the supporting guide therefor, the

sections beingin their normal position; Fig. 7 is a longitudinal section of the shiftable supporting means and supporting guide, one of the shelf sections being shifted on tothe remaining section; Fig. 8 is a top plan view of the shiitable supporting means, such as shelf sections, the same being in normal position and-the sup: porting guides; Fig. 9 is afragmentary view in section of the supporting guide and shelf sections being elevated disclosing the hinged connection of one of the shelf sections and the manner in which the roller Specification of Letters Patent.

leaves the slot formed the supporting guide; ,Fig. 10 is a fragmentary transverse sectional view of the supporting guide and shelf sections, one open, the other disclosing in detail the roller held within the supporting guide and the bracket member for said roller; Fig. 11 is a perspective view of the supporting guide'detached from the interior of the machine.

Reference being had to the accompanying drawings forming part of this specification wherein like characters indicate corresponding parts throughout the several views.

In the drawings the numeral 2 indicates a receptacle or casing of any desired shape and material, and having two covers 3 and 4 hinged to the upper edge of said casing 2. Said covers 3 and 4 are provided with beveled edges 5 so that when the same are in a closed position they will engage .with correspondingly bev eled edges 6 of the casing 2, thereby forming close joints and to prevent water when being sprinkled in the casing 2 from discharging through such joints and trickling down-the outside of the said casing. Each of the covers 3 and 4 is provided with handles 7 and 8, respectively, so as to open the same to allow entrance to the casing 2, and. when said covers are in an open position the same will be held at an inclination owing a to the beveled edges 6 of said casing 2 to allow the water sprinkled on said covers to drain into the said casing. Arranged transversely of the casing 2 and at the top edges thereof is a parting member 9 which divides the easing into twosections for the respective covers 3 and 4, and also serving as a support therefor.

At the interior of the casing 2 and near the bottom thereof are removable supporting trays 10 and 11, each having wire woven side 'walls fl2, and a wire woven bottom 13. One of the said walls 12 of each of said trays 10 and 11 is provided .with an extension 14 the same being perforated or reticulated as at 15 to produce a spray of water as the same is circulated in the direction of said trays for thoroughly spreading the water on to the articles supported in said trays. Extending from one'side to the other and at the top edge of each of said trays 10 and Llare bars 16 for holding in position intermediate the latterand the bottom 13 a convoluted or spirally arranged wire 17 iorming a rack for supporting articles vertically in said tieiys and to I afford thorough circulation of the water when the same is sprinkled on to the articles supported thereby.

I have provided supports 18 secured to the interior of the casing 2 so as to elevate the trays 10 and 11 a I distance from the bottom of the casing 2 and to allow the water drained from the articles in said to freely flow through the wire woven bottom 13 onto the bottom of said casing. e L,

Above the trays 10 and 11 are cross bars 19 secured, at the interior of the casing 2 a suitable distance from 1 10 each other, and hingedly connected thereto are tray sections adapted to be raised to an open position and when in such a position rest against stops 21 secured to the inner side walls of the casing, thus giving access to the lowermost. part of the latter. At the op-' 'under side thereof are further provided brackets 29 supporting the rollers 28. Said rollers 28 are adapted to traverse the trough-shaped supporting guides 22 when the said sections 30are being shifted on to the sections '20. Rotatably mounted within the supporting guides 22 are cog-wheels 31 which are adapted to extend up through the opening 27 in said support 22 and for engagement with a'plurality of rack teeth 32 depending from the under side of the sections 30 at opposite front corners thereof. Said cog-wheel 31 is adapted when engaging the rack teeth 32 to elevate the shelf sections 36 so that the same may be shifted above and on to the shelf sections 20, and also to release the frictional rollers 28 from their countersunk seats 33 formed in the bottom of the supporting guides 22, the said trays30 when-in their normal position, that is, not being shifted on to the shelf sections 20 1 have the rollers 28 seated in the countersinks 33 formed in the bottom of the supporting guides 22, and the said section 30 is at rest on the ledges 23 and 24 of the supporting guides. I

It is apparent that the countersinks 33 prevent the rollers 28 carried by the sections 30 from accidentally becoming displaced resulting in the moving of the tray from normal position on the supporting guides. When it is desired to shift the sections 30 the operator pushes on the sections 30 in the direction of the sections 20 so as to bring the rack teeth 32 into engagement with the cog-wheels 31 which will elevate the said sections 30 and after the cog-wheels 30 have traversed the rack teeth 32 the rollers then have left the countersinks 33 in the supporting guides 22 and are caused to traverse said supporting guides 22 throughout the longitudinal extent of the elongated slot over and on to the shelf sections 20, and after this has been accomplished if the operator desires to lift .the shelf sections 20 underlying the sections he raises the said sections 20 by its hinged connection to the bars 19 and during such movement the rearmost rollers 28 will be caused to move in an are through the openings 26, and the sections 20 and 30, respectively, are brought to rest against the brackets 21, thereby giving free access to the lowermost portion of the casing 2. For hingedly connecting th shelf sections 20 are provided extensions 34 having openings 35 connected to eyes 36 formed in the bars 19.

Interposed between the open wire sections and centrally within the casing 2' are rotatable paddle blades 38 and 39 carried by shafts 40 and 41, respectively. Said shaft 40 carrying the blade 38 includes two sections 42 and 43 and jointed to one another bya coupling sleeve 44, said shaft 40 being journalcd in bearings 45 and 46 having the usual ball bearings 37, and one end thereof terminating exterior of the latter in a pulley 47. Surrounding said shaft 40 is the shaft. 41 composed of a plurality of separated skeleton sections 48, 49, the same being connected by suitable fastonings 50,

and, when so. connected, one end thcrer rf is rotatably mounted on the bearing 45, and the other end having fined thereto a bevel gear wheel 51. which meshes with a bevel pinion 52 supported within the casing 2 by suitable brackets 53 and 54 at one side thereof. Said pinion 52 is adapted'to engage another bevel gear 55 keyed to the shaft 40 so that, when motion is imparted to the several shafts, the same will move in opposite directions, and will cause the paddle blades 38 and 39 respectively to traverse in a corresponding direction to the shafts upon which each blade is mounted. Said paddle blade 39 includes two plates 56 and 57, each secured to the respective skeleton sections 48 and 49 and braced thereon by the rods 58. To the uppcrcdgos of said blades 56 and 57 are bars 59, which hold the same separated a distance from each other to form a space 60 for the other paddle blade 38 carried by the shaft 40, and also to connect the said plates 56 and 57' and the skeleton sections 48 and 49 to form a unitary structure of the hollow shaft 41 It will be observed that, owing to the formation of the coupling sleeve 44, the same produces a bearing surface for the said shaft 4]. at one end thereof, and properly centers the same in relation to the other shaft. I

When the shafts have been put in motion, it will be observed that, owing to the arrangement of the gearing, one will be driven in one direction, while the other moves in the opposite direction.

On the outside of the casing 2 is revolubly mounted a driving wheel 61 having a handle 62, and which imparts motion through the medium of a belt 63 to the pulley 47 and to the respective shafts.

The casing 2 is held by a support including a base 64 having a rim 65 and legs 66 provided with the usual casters 67. To drain the water from the interior of the casing 2, I'have provided a cook 68. i It will be apparent that, by having the shiftable shelf sections movable over the hinged shelf sections, the latter, when brought to an open position, give access to the lowermost part of the casing, and, therefore, articles can easily be placed within said casing without the removal of a single section, and, when the respective sections are in a closed position, after having filled the lower parts of the casing and placed articles on the said sections, the same will be asserted in various localities around the revolving blades so that the water can come in contact with such articles and be th'oroughly cleansed. I

Secured between the hinged sections 20 and fixed to the cross bars 19 is an open wire section 69 forming a support for articles to be washed.

It is obvious'that the bottom of the casing is troughshaped, as at 70, and the same being slightly elevated at one end thereof causes the water and also any sedinient remaining in the latter to flow in the direction of the drain cock 68, which is situated at the lowermost end of said trough-shaped bottom.

Having thus fully described my invention, what I 1.
